Pros: "Flight attendants were friendly."
Cons: "Luggage that had to be checked at the gate was not immediately available when we landed."

Cons: "Breakfast could have been offered."

Pros: "N/a"

Pros: "The crew was nice. They did a very good job under the circumstance."
Cons: "The flight was delayed over an hour because of an error on Delta‘s part. They did not verify people as they were boarding. Further the person in 17 F was doing video chat as we were preparing to take off and he had very foul language throughout the flight. The crew never said anything."

Cons: "Delayed flight ruined it."

Pros: "Missed it"
Cons: "Give back money"

Pros: "Actually leaving the airport after 2 hours late was the best part."
Cons: "Not be hours late. And then when you finally land have to wait longer for an open gate cause they're doing work on the other ones. A lot of poor planning on this trip. Very disappointed in this experience cause I love to fly."

Pros: "Friendly crew. Landed early."

Pros: "The flight was average, but the quality of travel on Delta this year has been the worst I’ve ever seen. It’s average at best and I’m considering going back to American because I have yet to have a true Delta flight consistent with previous years, the whole reason I switched to Delta."
Cons: "Everything"

Pros: "Seat was comfortable"
Cons: "The temperature, it was kind of hot."

Cons: "The comfort seats are not that comfortable"

Pros: "This was my daughter’s first solo travel home from college. She said the staff was helpful and kind. She loved that the flight was not over crowded. It was a smooth flight."
Cons: "Only negative thing she could say was her flight was delayed an hour. But that isn’t terrible considering all the holiday travelers."

Pros: "Good customer service in person"

Pros: "chwcking in was very easy."
Cons: "No in board beverages. On flight from RDU to PHL beverages were served."

Cons: "I had a 4 hour layover in Minneapolis, there was another flight to Denver that I meant I could’ve been home three hours earlier had I done standby, but because I had a cheaper ticket I was not allowed that opportunity. That makes absolutely no sense to me seeing as my flight was packed. I’m sorry my flight saved me money"

Pros: "Not like"
Cons: "I have Sky Team Elite Plus Platinum but not fare anything!"

Pros: "the flight was quick and it was fine. flight crew was polite and professional."
Cons: "i didn’t like that my knees were in the row in front of me, and we hit some pretty scary bumps. i get really anxious about turbulence."

Pros: "Ease of check in and friendly people"
Cons: "Marta"

Pros: "Did not wait for luggage."
Cons: "Food was marginal. Equipment had low ceiling under carry on shelf. No entertainment."

Pros: "Delta provided great entertainment options and it felt like endless food and drinks. The seats were also a bit more spacious than usual"

Cons: "They cancelled my ticket and did not inform me. Horrible exlefywith JustFly.com Beware of this organization"

Pros: "The exit row seat on this leg out of PHL to SLC did recline! No need for Delta Comfort+ unless you want to get off of the plane ... faster."
Cons: "For some reason, the pilot couldn't figure out how to adjust the cabin temperature for the first hour or so. This made the flight (and I was sitting in an exit row seat, right by the door which is usually cooler) uncomfortably hot and muggy. Food? No food. Thank goodness for Delta Lounge (even if it was the one in PHL). Just snacks make this a poor option for many. I don't know what is up, but the USB charger on the two monitors didn't work and neither did the outlet between the seats. And I have two different sets of cables "just in case" and they're the 3-in-1 so I can try to charge multiple devices (Apple, Android and Samsung) but nothing worked."

Pros: "Staff personalities"
Cons: "Waited extra 20 mins after door closed to-complete loading luggage"

Pros: "Staff was very courteous, the flight was smooth."
Cons: "There was no TV's on this flight."

Pros: "There was one helpful lady"
Cons: "Flight was rerouted and rebooked twice. I’m stuck in Detroit overnight, and won’t be getting to Monterrey until tomorrow afternoon. Thanks, delta!"

Pros: "Uneventful flight - boarding was great and there were no hassles."
Cons: "No food. No onboard entertainment."

Pros: "The flight itself was fine."
Cons: "The flight was delayed and it set off a slew of connection problems."

Pros: "Flight attendants were really kind"
Cons: "We were an hour late to leave so I missed my connecting flight and am currently stuck in Minneapolis for nearly 8 hours now"

Pros: "Stewardesses were sympathetic but could do nothing."
Cons: "A few flurries out of Philadelphia and flight is delayed 2.5 hrs, we therefore miss our connection and all they wanted us to do was spend 2 days in airport until next flight. Finally reached a compassionate soul at customer service who got creative and routed us to BCN via ATL, Miami and Madrid."

Pros: "Got upgraded to 1st / Business class."
Cons: "Due to weather the power outage in ATL, the flight out of PHL was delayed by about 30 minutes. No movies. No meals."

Pros: "We were probably in the air for 30 mins; great short flight. Plane wasn’t filled so had plenty of space."

Pros: "Crew was very attentive and curtious. Boarding was a bit more chaotic than usual and the gate agent made no announcement about boarding procedure, which certainly contributed to the scrum resulting. I arrived from the Skyclub several minutes prior to boarding time and was unable to find a path through to the Priority Boarding Lane. As boarding began she had to redirect at least seventy-five percent of those in front of me as they were not in First Class. Had she made one or more clear announcements about boarding procedure I rather doubt such a misunderstanding would have occurred with so many."
Cons: "For the third Delta flight in a row (all First Class) the crew did not make any effort to keep economy class cuctomers form storing bags in the First Class overhead or using the only First Class laveratory during flight. This flight I was unable to utilize the laveratory even once due to this excessive and continuous useage. Trying to do my bit to reduce our carbon footprint, yet I am sorely tempted to return to charter service when disrespect of the airlines own basic service class rules gets piled on top of TSA hassles."

Pros: "I had a window seat"
Cons: "bumpy flight"

Pros: "Flight attendant insisted to take my jacket. She didn’t return led. I forgot jacket in Cincinnati"
Cons: "I need my jacket"

Pros: "As usual, Delta staff and crew did their best to make the flight quite enjoyable and smooth."

Pros: "one i got to gate i could relax"
Cons: "scary making connection from AA flight arriving int'l terminal"

Pros: "I appreciated the kindness of the staff at each of our stops. From beginning to end they were polite, helpful, and kind!"

Pros: "All crew was great"
Cons: "We lost checked bag or it was taken, will loss a half day shopping for replacements. Compensation policy very unclear, not counting on getting any."

Pros: "Arrived on time crew worked had"
Cons: "my seat was BAD , no recline- right by bathroom one of which was out of order."

Cons: "Compared to such airlines like Turkish or etihad, service and comfort was lacking behind."

Cons: "On time"

Pros: "Liked the plane and the leg room. Had to switch itenary due to weather and the gate agent did a great job."

Pros: "Airplane was good, boarding was fast."

Cons: "The original flight was canceled and a new one substituted - basically they wanted to fly a smaller aircraft (via a different regional carrier) so the flight number changed. PHL did not have the new flight info displayed at the Departures board or on the screen at the gate. Caused a little anxiety."

Cons: "Cramped, uncomfortable tin can of an airplane. Barely tolerable for even an hour’s flight."

Cons: "Delta Flight #1661 I paid for 1st class. My first flight was late so I arrived at the gate after boarding began. When the gate attendant scanned my ticket another printed. When he handed me the ticket my seat had changed to seat 25E. I told the attendant that I had paid for first class. He asked me to step aside while he contacted his supervisor, Joe. Then I had to wait until ENTIRE flight had boarded which defeated part of the reason I paid for the upgrade. This was on top of the fact I was so thirsty because 1st flight didn't have drink service and because it was late I had to book it to the connection arriving sweaty, hot and needing to use the bathroom. I was told they had given my seat away to someone as a free upgrade. Joe offered me a $100 voucher to take other seat which was less than I paid for 1st class, plus the seat was a middle seat in the rear of the plane. When I told him as much, he tried to manipulate me by telling me that they would have to kick someone out of my seat. When I declined the downgrade, they made me stand by while they kicked someone out of my seat which was embarrassing and humiliating. Then, when they handed me a new boarding pass, it was not the seat I had paid for and selected, instead it was in the first row, which I’ve always hated because there is no under seat storage and I cannot keep my backpack with me. When I pay for first class, it is primarily so that I can board first and so that I have extra room to work (which I need access to my bag to do). While I was trying to take out the minimum of the things I needed from my bag and figure out how to manage without it, 3 times a flight attendant told me they had to take my bag (since I was the last person to board they tried to prevent me from using the bathroom and they were anxious to leave early). I tried to explain that Delta had prevented me from boarding earlier and that they gave away the seat I paid for which was NOT the first row."

Pros: "Service was great. Seating was OK. It was a brand new vehicle, so the (climate/air handling) was great."
Cons: "Boarding was not well organized."

Pros: "I liked that I didn't have to pay for a carry on and the blanket they gave me in flight to stay warm it was a great flight."
Cons: "Only dislike was that the flight was ending other than that no problems"

Pros: "Flight left on time despite the problems"
Cons: "We waited for one hour to be able to board. The system crashed so we were very lucky to arrive very early to the airport"

Pros: "My father passed away earlier that day and I needed a ticket quickly to fly home. At the airport I was a mess and the airline counter attendant was so amazing helping me ( I had never flown United and had no idea about their luggage policies ect..). She quickly pulled me aside.. helped me with checking in and did her best to fine me another seat thatvwas better than the one I had already chosen.Also, she gave me a hug and her condolences. Flying with an airline that has heart helped me so much during one of the most difficult times of my life. I will absolutely fly with them again."
Cons: "No complaints ... but I paid for a movie to take my mind off of my father's passing during the flight and there was a short in my monitor for our whole row. It kept cutting in and out and "searching for signal", I only was able to see 1/4 of the movie I paid for with all the interruptions in signal."

Pros: "a little bit more foot-room than my previous flight on a different airline."

Pros: "Crew was great"
Cons: "Great aircraft!"

Pros: "Nothing"
Cons: "Delayed 3 hours"

Pros: "Tv"
Cons: "The tv kept shutting on and off"

Pros: "The leg room"

Pros: "Flight was disorganized because of maintenance issue"

Pros: "TV option"
Cons: "Confusing boarding status regarding priority (how did I get 5th) Had to check carry on bag Terrible leg room. Worst I've experienced. Knees hit seat in front Rough landing"

Pros: "United got me from point A to point B"
Cons: "Crew was rude, not just to me, but to other patrons. Flight was packed going and the man scanning boarding passes spoke to those of us asking simple questions as if we were stupid and defiant. Was he a prison guard in his previous job? On the way to Newark, I had an aisle seat. One of the stewardesses blazed by me with a cart ramming it into my shoulder without so much as a, "sorry." I'm not a big woman but maybe as I dozed off I leaned over a bit...There is no way she didn't feel her cart hit me. Rudeness, it seems is a part of the culture at United because the flight attendants coming back squeezed past the long line for the bathroom without saying, "excuse me." They did however, say, "I need to get by," and one of them brushed by the gentlemen sitting next to me and bumped his laptop and coffee. Overall it seems that the crew working these particular United flights have forgotten that we pay hard earned money to fly. Some of us are going on vacation, to see loved ones, and some are flying to deal with unpleasant circumstances. The staff may fly several times a day, but most passengers do not. There's a lot of prep and anxiety, that goes into taking a flight and a surly flight crew multiplies that anxiety. No one wants to fly with a crew that hates their job."

Pros: "Getting through the airport was a breeze"
Cons: "My wifi didn't work on board I was completely counting on it to work and I paid for it and it never actually connected me (so I wasted the money and didn't get a refund and I also missed an important online meeting!"

Pros: "The crew was nice and great with the three very young kids sitting in front of me. Left and landed on time!"
Cons: "Very cramped seating. The on flight entertainment kept searching for a satillite signal, only ever staying on for 30 seconds before searching for the next 3 minutes."

Pros: "Seats are comfy"
Cons: "Food service sucks"

Pros: "I'm handicapped and the help getting from terminal to terminal. The people were very helpful."
Cons: "I have metal leg braces. I had to remove them to get in the seat. So the flight was uncomfortable. It would be nice if the plane could have handicapped seating.I know I wouldn't have minded paying a little more for comfortable seating."

Pros: "Pilots and some flight attendants were kind and friendly."
Cons: "On the return home, I was seated in the last row right next to the lavatory. I was bumped into at least 25 times by other passengers and flight attendants. I would suggest removing the aisle seat on both sides."

Pros: "The crew did the best they could with what was presented."
Cons: "Pilot should of gave us accurate times rather than saying "we should be taking off in another 15 min folks" which turned into 4 hours, pretty crazy."

Cons: "Flight was delayed, missed connection, chose to go to Minneapolis and was booked on a flight that I didn't have time to get to the terminal, so was rebooked a 3rd time, missed my shuttle, have no idea where my luggage is"

Cons: "First leg delayed on Tarmac for over an hour so I missed my connection. Then united rebooked me for the next day but gave me no voucher or money towards a hotel so I had to get one myself since it was all night in the Houston airport.mthem the rebooked flight had mechanical problems we had to change airplanes, and gates/terminals and were delayed another 2.5 hours. It was terrible."

Pros: "noth"
Cons: "Nothing"

Pros: "Nothing"
Cons: "Plane was delayed due to fuel issue. Missed connecting flight and was put in economy when I paid for first class."

Cons: "My connection to YYZ was cancelled and I was not even rebooked to the next flight. I needed to buy a ticket on Air Canada in order to get there. Every time I fly United I find myself asking "why in the hell am I flying United?""

Pros: "Getting off the plane"
Cons: "Very delayed flight No updates for departure, empty desk until it was time to depart, for why we sat on the runway for so long, no update on landing time or that we were starting descent"

Pros: "The seats were comfortable. Staff was loud. But flight was okay. On time."

Cons: "Very rude crew."

Pros: "Good service"

Cons: "Showed up at gate to get my seat and attendants seemed flusterred and unprepared. It seemed that they were having trouble finding a seat for me and I could hear them discussing options with other airlines to get to my final destination"

Cons: "Either ran out of or no snacks offered. Crew seemed a little impatient"

Cons: "Where do I start. Let's start with booking and the lack of knowledge, inability to listen and respond in an appropriate manner, and the fact that after I asked to speak to a manager due to the previous issues with the agent, and after being transferred all I needed was some understanding and support due to a family emergency and instead I get a short rude push back and then hung up on by the manager after I expressed my struggle and desperation for help. The lack of empathy and just the overall experience was beyond horrible, and if it wasn't for the desperate situation I was in I would have never used your services."

Cons: "I didn't like that on the way to Philly I could watch movies on my device, but on the way back I would have had to pay to use the seat-back system."

Pros: "On time bags made connection"

Pros: "Crew very friendly!"
Cons: "No entertainment (video screens ) on board flight."

Pros: "It was a light flight, so I could have my carry-on with me even though I was in group 5. The breakfast -- berry pecan French toast -- was surprisingly tasty and satisfying (if not very attractively presented)."
Cons: "Too bad I had to pay so much for the exit row seat. I'm tall and it's needed for standard comfort (as opposed to extra comfort). Oh well. Gotta squeeze those dollars out of the passengers every way they can."

Pros: "The boarding was very smooth."
Cons: "The passengers behind me had a baby on board that cried throughout the whole flight."

Pros: "Boarding was efficient and the crew was competent."
Cons: "United charges you extra for everything. Economy is uncomfortable."

Pros: "In Flight staff very nice"
Cons: "Delays delays"

Pros: "Nothing!"
Cons: "My first time flying through United and I am dissapointed my flight was delayed over 6 hours and we get no refund for that? Really United? Aren't you suppose to be a top airline for a reason. Never again"

Pros: "Friendly service, nice and comfortable."

Cons: "The seat cushions were in terrible condition!!!"

Pros: "Departures and arrivals were on time. Boarding was efficient. Baggage arrived in claim area quickly. No stress or hassle."

Pros: "Crew was attentive and efficient."
Cons: "Seats are very cramped for anyone above average height. Not enough space for carry on baggage when the plane is full."

Pros: "The flight staff were courteous."
Cons: "The seats were too tight I was squished to the window by big person next to me and the person front of me reclined to tighten up the space more. My seat could not recline"

Pros: "Nothing no transparency"
Cons: "Everything no compensation no assistance upon arriving to Houston four hours late for connection... Had to rent a car to get to San Antonio"

Cons: "Cross country flight, tiniest snack ever, $8 for any entertainment. Choose JetBlue if you get the choice"

Pros: "It was awesome fckin amazing"
Cons: "Nothing"

Pros: "Arrived on time despite having to swap planes because of faulty equipment."
Cons: "Should have inspected plane sooner and should have better maintenance program."

Cons: "I paid for my luggage in advance and when I arrived at Philly airport it was not acknowledged"

Pros: "Returned flight from Phily was ok and on time"
Cons: "The first part of my flight was cancelled after the passengers were boarded. Then long lines to make changes. I had to booked with American Airlines to get to Phily"

Cons: "Every time I fly through San Franscisco, my United flight is cancelled, delayed or I get stranded! If you know a large number of your passengers are coming in on a flight from the east coast that was delayed for de-icing...wouldn't it be easier to just hold the flight, since it is the last flight of the night. United's customer service and care of passengers is horrible!"

Pros: "acceptable for the price"

Pros: "This was the best flight."

Cons: "I was asked to change my flight. I did so out of the goodness of my heart. I then went to check into my new flight and I was told I wouldn't probably be put on it. Although it was eventually corrected, it was unnecessary frustration."
